Abstract
With the rapid development of the mobile internet and intelligent technology of in-vehicle equipment, the Internet of Vehicles (IoV), centered on intelligent connected cars, has gradually entered people’s lives. However, these technologies also bring serious privacy risks and security issues in terms of data transmission and storage. In this article, we propose a blockchain-based authentication system to provide vehicle safety management. The privacy and security attributes of various vehicle authentication transactions are based on high-level cryptographic primitives, realizing temporary and formal authentication methods. At the same time, a fair blockchain consensus mechanism Auction of block generation Rights (AoR) is proposed. To demonstrate the feasibility and scalability of the proposed scheme, security and performance analyses are presented. The relevant experimental results show that the scheme can provide superior decentralized management for IoV.
Highlights
In recent years, as a potential technology, the Internet of Vehicles [1] has attracted great attention, bringing a better life to human beings
Consensus Process. e Auction of block generation Rights (AoR) consensus assumes that the number of ordinary nodes is Nu, the number of commissioners appointed from ordinary nodes is Nc, and each auction interval is Tw. e vendee is determined within time Ta, and a new block needs to be generated within the time Tb, Ta + Tb ≪ Tw. e valid block records the whole process of the auction transaction and gets (Nc/2) + 1 commissioners’ signature at least. is process is known as a round of consensus
Due to the actual untrusted environment, establishing trust in Internet of Vehicles (IoV) is a critical security issue. erefore, we proposed an authentication with optional privacy preservation
Summary
As a potential technology, the Internet of Vehicles [1] has attracted great attention, bringing a better life to human beings. E Internet of Vehicles usually consists of a large number of static basic settings and dynamic vehicles as the main participants in the system It is equipped with advanced in-vehicle sensors, controllers, actuators, and other devices and integrates modern communication and network technologies to realize the information exchange and sharing between vehicles and vehicles, roads, and service providers. Authentication is considered the first line of defense against malicious vehicles and messages [5,6,7] It is the basis for the security of all other applications of the Internet of Vehicles in the open traffic environment. (1) For high real-time requirements, we propose a decentralized vehicle registration with TA providing authentication keys for each RSU.
